RE: [Tutor] Is python just a scripting language?

There should be compiled scripts too - files ending in .pyc These load slightly faster than scripts and can be distributed if, for some reason, you want to protect your source code from scrutiny. The freeze tool for producing executables is somewhat limited and produces rather big files since, as far as I can tell, it basically bundles up the interpreter and all required units into a big binary!

I would like to have recommendations on which version of Linux to purchase. I would like to learn the Python Language and would like the opportunity to read open source code but I am unfamiliar with any other operating system except windows. Thanks Sam LeFlore

Tkinter radio buttons
by Alan Gauld Dec. 25, 1999

Dec. 25, 1999

I tried a simple radiobutton app but the suggested behaviour didn't happen. I needed to add a command function. Is this normal in Tkinter or am I missing something? The code below doesn't work, but will if you uncomment the commented out lines. I thought Tk should update the variable automagically...? Alan G. -------------------------------------- from Tkinter import * rv=0 def DoIt(): print rv #def doZero(): # global rv # rv = 0 #def doOne(): # global rv # rv = 1 app = Frame() r1 = Radiobutton(app, variable=rv, value=0, text="Zero", # command=doZero ) r1.pack() r2 = Radiobutton(app, variable=rv, value=1, text="One", # command=doOne ) r2.pack() r1.select() b = Button(app, text="Showme", command=DoIt) b.pack() app.pack() app.mainloop()

dbg
by Ben Beuchler Dec. 24, 1999

Dec. 24, 1999

I've read the documentation on the debugging module but a lot of it went right over my head. I've written a rather large (for me, anyway) script that I would like to step through to make sure it's working properly. Is there a nice, simple way to step through a python program while monitoring the state of a few variables? Thanks, Ben

"It doesn't know what w1 is"... sounds like some variable names are messed up, or declared locally rather than as class attributes, or a missing self, or something like that. :) To be more specific, I need to see more code. If it's a lot, you can mail it to me privately, otherwise you can post it to the mailing list so others may shed their light on it too. --Hans Nowak (zephyrfalcon(a)hvision.nl) Homepage: http://fly.to/zephyrfalcon You call me a masterless man.

Re: Classes!Classes!Classes!
by Christopher Grove Dec. 23, 1999

Dec. 23, 1999

I have just started investigating Python, and want to jump in with class questions (to verify if I have gotten to the 'aha!' stage mentioned earlier. Can classes be composed of other (sub)classes? Can classes be composed of multiple copies of the same (sub)class? [I apologize for bastardizing any terminology here, I am trying to put it in my own words (because they are what I understand best).] My self-determined example is house design and definition: House(class) Living room(class) room(class)[1] light(class)[0..n] lr furniture (or would I have multiple classes here, sofas, chairs, tables, etc) color (or would these be attributes of the floor, ceiling, walls) Kitchen(class) room(class) light(class) kitchen furniture kitched appliances . Bathroom(class)[1..n] . Dining room(class) . Bedroom(class)[1..n] room(class) light(class) bedroom furniture . . Room(class) Ceiling(class)[1] Floor(class)[1] Wall(class)[1..n] description dimensions . . Ceiling(class) Composition Color Light(class)[0..n] Fan(class)[0..n] Dimension Wall(class) Composition Color Dimension Window(class)[0..n] Door(class)[0..n] Light(class)[0..n] Lights can be part of the ceiling or wall, or free standing. Can the (sub)class defintion be placed at different levels in the class heirarchy? Do I have to (should I) segment walls (i.e. composition, part of the wall painted, part wall papered, or part painted and part wainscoated, or part ...)? I suppose if I were designing a mansion, I'd have the opportunity for multiple kitchens, etc.

(no subject)
by Barth Bellot, S.L. Dec. 23, 1999

Dec. 23, 1999

I have just started to get familiar with Python - Python may soon become what once used to be Turbo Pascal on the 80286/80386 platforms... My problem: I would like to get the main window app packed in its own class and every other window packed in a different class. Unfortunately all docs I have found treat these subject in a functional and not object oriented style. The biggest problem is the Main Window Menu. I would be very graceful for a couple of example lines which show how this can be done.

RE: [Tutor] input command

> I am very new at this so please bear with me. > > When I try the "input" command it seems to automatically > print when I try to > go to the next line. input is for numbers only! You may need raw_input()... But it sounds like you are typing this in the interactive prompt mode. You probably need to type your program into a separate file and then run that from the Unix/DOS prompt like: C:>python myprog.py Visit my tutor and look at the 'Talking to the user' and 'modules and functions' sections... http://members.xoom.com/alan_gauld/tutor/tutindex.htm If you really want to do it from the interactive prompt, simply type in your value and hit return. This will return you to the >>> where you can carry on inputting your program. The value you entered will be stored in 'a'. Thus: >>>a = input ("Hit it: ") Hit it: 12 >>>print a 12 >>> Alan G.
